The fastening system is also very important in determining the maximum load capacity of shelving. Light duty wire shelving with tubular steel uprights typically utilizes a plastic collar fastening system. Medium and heavy duty shelving systems utilize a boltless design that incorporates single or double rivets to join the front/side supports to the uprights via the punched holes. Extra heavy duty or high capacity shelving is either bolted or permanently welded together, or may utilize special high strength, boltless fastening systems designed for extra heavy duty applications.
